Can You Recover Lost Data?

In a nutshell, recovering data means that someone has to try to salvage inaccessible data from a corrupted or damaged storage site. Think computers and how they crash, sometimes inexplicably and you are suddenly left with nothing.

That feeling of helplessness when your computer crashes leads you to an expert in data recovery. Sometimes they are successful and sometimes they aren’t but they are all trained in salvaging files from storage media like external hard disk drives, solid state drives, USB flash drives, CD’s, DVD’s, and magnetic tapes.

Data recovery can be needed for different things, the most common is an operating system failure but computers can also be damaged by physical damage and things like tornadoes, flooding and hurricanes; things that are deemed ‘acts of God’. Then of course there is the good old virus or Trojan Horse that gets into the computer and renders it in need of quick and professional assistance.

If you have the most common type of data recovery it will be because of an operating system failure and in that case the technician will try to get your files on to an other device. If you have a drive level failure and/or a compromised file system or hard drive disk failure the data may not be as easy to recover and read. In this case the technician would try to repair the file system itself, and luckily some damage may be able to be repaired by replacing parts of the hard disk. If there is still damage there is a specialized disk imagining procedure that can be undertaken to try to recover every readable bit of the data that can be reclaimed. Then the files can possibly be reconstructed.

Usually if your computer crashes and you need a data recovery expert you will take the computer to them, but other times they have to do their work remotely either because the system is just too big to take in or just too far away for it to be possible. This of course requires a lot more skill and expertise in the field.

Simply, then there are four phases of data recovery. Repair the hard disk drive, image the drive to a new drive, logical recovery of files and repair retrieved files. Once all four steps have been taken, we hope that your computer is up and running again, and it should last-until the next time you experience a crash.

How to Find the Best Data Recovery Software for You

Selection of the best data recovery software is crucial if you want to ensure a successful recovery of your lost data. But, the problem that people face when looking out for the best software is “they read product reviews.” Maximum of such reviews are paid; therefore, they are product centric. In many reviews, you will not even see a single “flaw” of the software. How it is possible that the software does not have even a single fault? Was that designed and developed by a team of angles? So, you need to be aware of such paid reviews when looking out for an efficient software to recover the lost data.

In this article, I will take you through some steps that can help you find the best solution help you recover the lost data from Windows or Mac machines. In addition to Windows and Mac, you will be able to perform data recovery on pen drives, memory cards, cameras, etc.

Best Method to Find a Perfect Data Recovery Tool

First of all, you need to forget all reviews. You do not need to stick to any specific brand as well. You should rather inspect the functioning of the tool, its simplicity, and its accuracy. So, let’s start finding a good solution to perform flawless data recovery.

Step 1 – Start a Web browser.

Step 2 – Open Google or Bing.

Step 3 – Type “Data Recovery software companies” in the search bar.

Step 4 – Visit websites of a few companies in separate tabs.

Step 5 – Download the trial versions of the software of the different companies.

After this, we need to prepare a setup to test these trial versions. Before we go ahead, I would like to mention that “the free trial versions of these software” work similar to the paid versions, but you are not allowed to save the recovered data. You can check the worth of the recovered data, but to that a licence will need to be purchased.


Do not use the free trial version on the device from which you want to recover the lost data, because if it does not work well, you may not be able to get back the lost data even with another tool. That’s why, after Step 5 above” I mentioned the need to prepare a setup.

Preparing Setup for testing the Best Data Recovery Software

  • Move the free trial versions of the tool on any other computer. Note that this PC should not be the one from which you need to perform the actual data recovery.
  • Now install the first trial version.
  • After this, delete some files, folders, etc. using the SHIFT + Del key. This key deletes the data without moving it first to the Recycle Bin folder. You can also format a partition to perform the recovery.

Testing and Finding the Best Software to Recover the Lost Data

  • Once the deletion process is completed, launch the free trial version.
  • Browse the hard disk partition from which you have deleted the data. If you have formatted a partition, select that.
  • Start the scanning process.
  • Now, stay relaxed and do whatever you want to do because this process will take some time depending on the amount of the data to be recovered.
  • After the scanning process has been completed, you will see a list of the data recovered from the selected hard disk partition.
  • Analyze that data based on the percentage of recovery, quality, etc.
  • If you find that more than 60-70% recovery has been done and the quality is good as well, you can purchase a license key for this Data Recovery software. If the percentage of recovery is less than 60% or the quality is not good, you can uninstall this trial version and repeat the above process once again until you find the best software to recover the lost data.
  • After you have come across the best software, install its licensed version on the PC where you want to perform the recovery and run it.

CautionPlease note that in the case of severe corruption, the percentage of data recovery can be less than 60%, but in such cases, few software often provide raw recovery. You may want to go ahead with that solution as well.

Software providers, who are professionals, leave a mark on their website, which is easy to recognize for people. According to the experts, an excellent website separates the best from the rest.

Take a Look at the Testimonials Page

The testimonials page of the company website speaks a lot about the company. People can know about the reviews from the previous clients of the company. If there are no testimonials, it is better to stay away from the service provider. Such pages on the website of the company speak on behalf of the reputation and validity of the company, and helps people stay sure of the service quality.

Free Assessment is Must

An assessment is necessary to find the problem of data loss. Though many companies charge separate amount for the same purpose, it is not a valid thing. Reputed service providers do not charge for an assessment.

Trends of Data Recovery in 2016

From the ancient times, data is the most wanted asset of an organization. As the digital storage methods were adopted, the data loss was the troublesome area for the organizations. Many IT tools and organizations like Oracle, SQL, became famous for managing data resources.

Moving from the digital old methods to manage big data centers have not invented any method in which we can have zero data loss during the data recovery process.

The advanced technologies like cloud storage, virtual storage, data mining and warehousing techniques are developed by the IT professionals. But none of the methods could satisfy the need of the organizations to save the data for the long time without any loss.

The IT experts and the Financial Analysts have come to a conclusion that a big storage cart and a huge team can not be the solution. It is seen that many organizations have closed their local server storage rooms, personal data centers, etc.

Instead, a hybrid data collection model is adopted which allows organizations to store the data on the remote resources by maintaining private cloud or public cloud infrastructure.

In accessing, maintaining and recovering the data, security has become a major issue which has forced the IT professionals to invent new methods of data storage and data recovery.

Many organizations are implementing the concept of common storage. This has reduced capital expenditures (CAPEX) and operation expenditures (OPEX) with the ability to quickly scale and recover the data from an old resource.

In 2015, a complex, high-end software defined storage (SDS) systems was the top trend which has changed the viewpoint of data recovery. The trends include the need for better data privacy and security along with the enhanced legacy of the data management technologies.

The four major transformations in the storage of the databases will be:

1) Data Protection as a service initiative
2) Database as a part of the cloud service
3) New aligned apps for the DBA and application heads will be introduced in 2016.
4) A well defined DBA role to maintain oversight of data protection to get zero loss on recovery

According to the market survey, the global storage will be double in the volume by 2019.The major services adopted by the organizations in the 2016 are:

1. Use of cross platform approach in the diversification of data creation and storage

The different organizations are relying on the techniques to keep the data in the remote. Cloud storage has become one of the most demanding ways of storage. As the data is stored in the variable formats using the standard tools. A centralized recovery of data irrespective of its origin is preferred for the future use.

Data Loss Prevention (DLP) techniques are in the market for the last 10 years, but many do not pay attention to them because of the high cost. A normal DLP process involves:

1) Maintenance of confidential data to be private only
2) Control over out flow of data
3) Implementation of the standard software’s with the licensed versions of full data recovery
4) A virus free data with the defined data dictionaries and source file coding

2. Raised demand to develop disaster recovery capabilities

The dependency on the digital storage is 100% now. The disaster recovery methods can only prevent the companies data in case of total database failure. Moreover the social and environmental issues are having an impact on the data storage methods. In the year 2016, the trend of making the duplicate copies of the data is going to be followed.

The top disaster management methods will include:

1) Hybrid-infrastructure is the only solution for future prevention of data.
2) Tie ups and alliances are causing major difficulties in recovering old data. The use of data center will be the right option in such cases.
3) Transfer of data from one platform to another causes loss of original data definition and integrity which needs to be preserved. A standard format which is convertible has to be adopted to have minimum loss.

3. Implementation of emerging IT platforms into existing infrastructure

In the last 10 years, many repositories are being created to serve the various sectors like IT, health care, financial sector, etc. The responsibility of maintaining them is taken by the IT companies. This is providing high recovery rate and also assuring the privacy of data. A new IT trend is to attach the repositories with the clouds. But the requirement of using new innovative techniques to create lighter clouds are required. In the year 2016, we will keep on researching on the methods to create such platforms and to transfer more and more data into the clouds with the extended security and privacy options.

In the year 2013, a new wave of “doing by yourself because you know your data better”, started. The time spent in explaining organizational data to outside IT company was a tough process.

The ERP software is used for the big data storage and recovery. The IT companies are able to recover data in a better way now. The same trend will be followed in 2016.

4. Mission of shorter recovery time and objectives for penetrating environments

The IT professionals are always working under pressure to provide new methods for the database recovery. They have developed short recovery modules without any data loss. But these modules need to be customized according to the data required. Hence the development of such environments is always demanding. They require proper formats of the databases. The maintenance of business data, emails, financial data and other important data which is an asset to the organization has become a painful area for most of the old organizations. In such a dilemma, the organizations are not able to opt for the best technology.

The objective in 2016 will be to apply and recover most of the data of such organizations. The virtual data methods will be applied by using automatic cleaning and modifying tools.

5. Performance-oriented services with the raised price in 2016

The volumes of data are increasing, backup and recovery of data are becoming difficult and the profit margin in updating such big volume records is less. The new term called recovery per unit data loss is becoming the criteria to set the pricing for the recovery. The prices will be more to recover per volume of data with the low data loss in 2016.

The proactive measures to recover data increases the comfort and if this is done on the regular basis then the chances of maintaining accurate data with less redundancy increases. The new methods of dividing the data on the basis of categories never permits to raise the volume very high.

So, finally the followed trends of 2016 in data recovery will be opting for the cloud storage and more of virtualization techniques. The data recovery will move around the four terms

Cloud: Data protection as-a-service.
Mobile: Push data out to the edge.
Social: Defining new formats of data.
Big Data: Protection of more needful data.

Three Tips On Choosing A Reliable Hard Drive

The humble hard drive is a standout amongst the most neglected PC segments nowadays. At the point when purchasing a PC, a great many people consider just the storage room accessible; they regularly overlook the various contemplations that make it a decent or awful buy. While this might be fine for the light PC client, a hefty portion of us store delicate or essential data on our hard drives, and execution and dependability are principal. Notwithstanding, it can be hard to recognize what to search for when purchasing a hard drive – the sheer measure of specialized information can be overpowering. So here are three useful tips to help you when purchasing a hard drive.

Try Not To Purchase Restored

This is a standout amongst the most imperative tips. Hard drives have a constrained lifespan at any rate, and in purchasing a revamped drive, you naturally relinquish some of that time. The cost might be incredibly low, however that is simply because you are surrendering a portion of the dependability to which you are entitled when buying a bit of gear. Restored drives are ones with which somebody has officially found an issue, and in spite of the way that the issue might be settled, the drive is presently basically harmed merchandise. It looks bad to endow your private and/or urgent data to a bit of equipment that has as of now been hailed as broken. In this way, pay a smidgen additional and get a fresh out of the plastic new drive.

Purchase From A Trusted Producer

There are numerous hard drive producers in the business sector today, and in like manner, there are shoddy and inconsistent drives all over the place. In case you’re even modestly keen on PC segments or gadgets, you will probably as of now have known about a few makers who can be trusted to furnish you with a first rate bit of equipment. Western Digital, Seagate and Samsung are three of the most mainstream producers, and generally they can be depended upon. Obviously, the most solid hard drive is all that much a matter of assessment and the answer will be distinctive relying upon whom you inquire. When in doubt, be that as it may, in the event that you’ve never known about the producer, and you can discover sparse data about them on the web or in PC magazines, stay away.

Research Your Requirements

This might appear like an easy decision; however appropriate exploration is your most significant instrument when acquiring another one. You ought to research what you will require; for instance, will the working framework be running on the drive? Assuming this is the case, you ought to purchase one with a genuinely high RPM to guarantee that your drive won’t be the bottleneck (the constraining element) in your PC. Will it be utilized for the most part for media stockpiling, or other non-escalated errands? Go for one of the “green” drives from the producers specified above; they have lower force use and a lower twist speed – also, they are frequently very modest. Hard drives have numerous qualities and characteristics, and realizing what every one means helps you to all the more unequivocally distinguish precisely what you will require, and along these lines the amount you will need to pay.

These are only a couple of the numerous things to consider when purchasing a hard drive. Be that as it may, tip three will ensure you generally know precisely what you are doing, and why. By taking after these rules, you can make sure you’ll purchase a solid one that can be trusted with your imperative information.

Think You Have Cloud Data Protection? You Need an MSP More Than Anyone!

Sounds crazy, right? Almost all our clients have a hard time believing that statement the first time they hear it. Since they have trusted all of their critical IT applications to the Cloud, they believe cloud data protection is just part of their package: that “someone” is watching over their applications to ensure they run perfectly and safely.

Unfortunately, that’s 100% totally wrong. In fact, this belief in automatic data protection in the cloud can and will bite you harder than you can imagine.

The Data Protection You Really Get

Here’s an example. Recently, I took a call from a prospect about managed services, and after we talked for a little while, I asked about his business continuity process. He assured me everything was handled by his various cloud providers and his data was safe. I replied, “Call one of them and ask specifically about data backup.” He was curious enough and said he would.

A few hours later, I got a call and the prospect was in a bit of a panic. His Cloud provider said that backup services were not included in his package, but they could add cloud data protection. The vendors follow up question was “Who is going to be the point of contact to get error messages and verify the backup was working?”

My prospect was stunned. He explained to the Cloud provider he assumed they would be the point of contact. Of course, they said no. Their business provided the service and he needed someone responsible to check whether the backups were in place and verify whether the cloud data protection was working according to his needs. The Cloud provider offered cloud capabilities that could solve his IT needs, but did not offer a service that verified everything was working and he was properly protected.

Imagine my prospect’s surprise at thinking his data was safe, when in fact it was not. He was very upset at the Cloud provider for not informing him sooner. They had assumed he knew what he was ordering. The level of cloud data protection he was receiving was clearly spelled out in his contract. My prospect quickly understood no one was watching over his critical data and processes. He was on his own.

Backup Rarely Comes Standard

Unfortunately, the situation got worse for my prospect. I also explained that his features in Office365 was a great system, but he should have someone managing his backup for email. My prospect responded with “But surely Microsoft can recover email forever. It’s just Exchange in the Cloud and their cloud is huge… ” I said yes, but even Office 365 has limitations and if he was not aware of those limitations, he could easily have issues recreating critical data.

Plus, Exchange in the cloud still needed someone to setup email addresses, control security, help with desktop applications, etc. Again, moving the technology to the cloud did not remove the need for a person to constantly manage the application. The cloud was definitely a better delivery mechanism, but people still had to be involved.

Who Handles Cloud Data Protection & Backups

The Cloud is a great technology and our clients use it every minute of the day, but as with all technology, the Cloud needs proper care and nurturing. Without such attention you will lose data and business productivity, the same as if your technology was onsite.

That is the value of a managed service provider.

Eliminate Your Fear About SQL Server Error 18456

The SQL Server database is a Relational Database Management System, which is used in across the globe. And just because SQL is used so widely doesn’t mean it is immune to errors. A common error faced while logging into the SQL server is error 18456 and this is the error message that is displayed on the screen –

Login failed for user. The user is not associated with a trusted SQL Server connection.

When users try to connect to the SQL Server through the login authentication system, instead of granting access to the user, the server throws error 18456. Sometimes the error also says that it is state 1, which is almost the same as the main error because all the other variations of the error 18456 are converted into state 1 error because of security reasons.

As you can see, Microsoft isn’t as helpful when it comes to providing details about error messages.

Reasons behind SQL Server error 18456

    • Authentication issue: First login from the new system can also be the reason of this error. The good part is – it is nothing major. The error is being thrown because the server is set to Windows Authentication mode. Change the mode and try logging in again. The error should be resolved
    • Wrong credentials: This is probably the most common reason for error 18456 and yet, we like to focus on the minute details. Check if your credentials are right. If you are logging in for the first time, make sure you received the right credentials from the administrator.
    • UserID disabled: If the UserID hasn’t been granted access to the SQL Server then this error will be thrown. Again, if you are trying to login for the first time, we would recommend contacting the administrator to make sure that your UserID has been granted access.
  • Different states of the error: As we mentioned there are different states of the error and once you know what the different states mean, it is easier to resolve the problem:
  1. If the error state is 2 or 5 then that means the UserID is invalid and you need to check that.
  2. Error State 6 means the user is trying to use a Windows Login name for SQL authentication which the server is not able to understand.
  3. An error state of 7 means that either the login has been disabled or there is a password mismatch
  4. Error state 8 means there is a password mismatch
  5. Error state 9 implies invalid password
  6. Error state 11 and 12 means the login details are correct but there is a server access failure.
  7. Error state 13 implies the SQL server has been paused
  8. Error state 18 means the password has expired and it needs to change

If the error state is something else than this, then it is probably an internal error and before doing anything you should contact your administrator.

Final Words: SQL Server 18456 error is a login error which can be easily resolved by a few troubleshooting steps. Most of the times, the issues can be resolved instantly. Make sure to always cross check your credentials before doing anything else.
